Jan 8, 2024

Datasets & transform refactoring

• HuggingFace streaming (iterable) dataset support (--dataset hfids:org/dataset)
• Webdataset wrapper tweaks for improved split info fetching, can auto fetch splits from supported HF hub webdataset
• Tested HF datasets and webdataset wrapper streaming from HF hub with recent timm ImageNet uploads to https://huggingface.co/timm
• Make input & target column/field keys consistent across datasets and pass via args
• Full monochrome support when using e:g: --input-size 1 224 224 or --in-chans 1, sets PIL image conversion appropriately in dataset
• Improved several alternate crop & resize transforms (ResizeKeepRatio, RandomCropOrPad, etc) for use in PixParse document AI project
• Add SimCLR style color jitter prob along with grayscale and gaussian blur options to augmentations and args
• Allow train without validation set (--val-split '') in train script
• Add --bce-sum (sum over class dim) and --bce-pos-weight (positive weighting) args for training as they're common BCE loss tweaks I was often hard coding

Nov 23, 2023

• Added EfficientViT-Large models, thanks SeeFun

• Other misc fixes
• Release 0.9.12

Nov 20, 2023

• Added significant flexibility for Hugging Face Hub based timm models via model_args config entry. model_args will be passed as kwargs through to models on creation.
  • See example at https://huggingface.co/gaunernst/vit_base_patch16_1024_128.audiomae_as2m_ft_as20k/blob/main/config.json
  • Usage: https://github.com/huggingface/pytorch-image-models/discussions/2035
• Updated imagenet eval and test set csv files with latest models
• vision_transformer.py typing and doc cleanup by Laureηt
• 0.9.11 release

Nov 4

• Patch fix for 0.9.9 to fix FrozenBatchnorm2d import path for old torchvision (~2 years )

Nov 3, 2023

• DFN (Data Filtering Networks) and MetaCLIP ViT weights added
• DINOv2 'register' ViT model weights added
• Add quickgelu ViT variants for OpenAI, DFN, MetaCLIP weights that use it (less efficient)
• Improved typing added to ResNet, MobileNet-v3 thanks to Aryan
• ImageNet-12k fine-tuned (from LAION-2B CLIP) convnext_xxlarge
• 0.9.9 release

• 0.9.9 release

Oct 20, 2023

• SigLIP image tower weights supported in vision_transformer.py.
  • Great potential for fine-tune and downstream feature use.
• Experimental 'register' support in vit models as per Vision Transformers Need Registers
• Updated RepViT with new weight release. Thanks wangao
• Add patch resizing support (on pretrained weight load) to Swin models
• 0.9.8 release

Small bug fix & extra model from v0.9.6

Sep 1, 2023

• TinyViT added by SeeFun
• Fix EfficientViT (MIT) to use torch.autocast so it works back to PT 1.10
• 0.9.7 release

Aug 28, 2023

• Add dynamic img size support to models in vision_transformer.py, vision_transformer_hybrid.py, deit.py, and eva.py w/o breaking backward compat.
  • Add dynamic_img_size=True to args at model creation time to allow changing the grid size (interpolate abs and/or ROPE pos embed each forward pass).
  • Add dynamic_img_pad=True to allow image sizes that aren't divisible by patch size (pad bottom right to patch size each forward pass).
  • Enabling either dynamic mode will break FX tracing unless PatchEmbed module added as leaf.
  • Existing method of resizing position embedding by passing different img_size (interpolate pretrained embed weights once) on creation still works.
  • Existing method of changing patch_size (resize pretrained patch_embed weights once) on creation still works.
  • Example validation cmd python validate.py /imagenet --model vit_base_patch16_224 --amp --amp-dtype bfloat16 --img-size 255 --crop-pct 1.0 --model-kwargs dynamic_img_size=True dyamic_img_pad=True
